Bioinformatics & Data Science. I’m not sure how to put it, but I **really** enjoy making charts.

30 Day Chart Challenge 2026

Rodrigo Barreiro @rodrigo404.bsky.social · 30/04/2026

I did it! 30 days of the #30DayChartChallenge 🏁 To survive, I used 22 R packages, forced a single color palette on everything, and shamelessly reuse of datasets. check out the full gallery + code here: below. catch me eating lunch in a non-grid format now. ✌️

#30daychartchallenge / day 08 / circular It would be beautiful if the data had more variation (look what I’ve become, blaming the data lol). Also, it would be cool if I could add a legend with an image.

30 Day Chart Challenge 2026

Rodrigo Barreiro @rodrigo404.bsky.social · 04/04/2026

i've finished my gallery for this year #30daychartchallenge! now, only more 24 charts to go, yay

Rodrigo Barreiro @rodrigo404.bsky.social · 04/04/2026

Absolutely, it would be better if data had the same magnitude so it could share the same axis. Also, the delta could be added in the middle to better quantify the difference. the facets could be sorted by delta, so we would have a better ranking information about the deltas too

finally, the first week of #30daychartchallenge this year I think I would not be able to keep making one plot by day, so things may get out of hand :/ note, there used to be this thing called CDs which we used to listen to music (feeling old)

Let’s go to another #30daychartchallenge I’m so rusty i forgot it took so long to adjust legends. This my main focus is to survive until the end of this without make myself (more) crazy.
